Before I had my fall and landed on my head on the concrete curing the vertigo, I was managing it with simple training. Just as your eyes do when they put together several inputs to make a clear picture based on experience. Sight is not as clear as it seems, especially in regard to 3D. Its all a brain trick that you learn as you grow up.
I also have tinnitus in my ears and my brain has learned to ignore it. I dont notice it unless the subject comes up....like right now....otherwise my brain filters it out as "Fake News". So I decided that I could do that with vertigo.
Vertigo is a false signal that you are listing to one side or the other when you actually are not. So whenever I started to feel that sensation I would say to myself, "Fake News, Fake News" and sure enough my brain began to respond by ignoring THAT input and relying instead on my visual input and my muscle tension. It wasnt fast, took a while, but it worked very well. Its just a matter of recognizing the fake signal and then adapting other senses to it.
I also was diagnosed with Trigeminal neuralgia which is a very painful condition that affects the side of your face. Its another "Fake News" situation. The side of your face feels like it is on fire. I tried the same tecnique, telling myself that my face was NOT on fire and again after some retraining it worked. Only downside to that one is that if the side of my face ever does catch on fire I will not know it till the smoke gets in my eyes.
